Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1703250 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Voltage rating (600V UL) and current capacity (5A) must match exactly
Mechanical Configuration: 6 positions per level, 0.400" (10.16mm) pitch, and PCB pin straight rear connection must be identical
Interface Type: Front panel female socket header connection is mandatory
Panel Mounting: 2-piece snap lock mechanism with compatible panel thickness range (0.039 ~ 0.118")
Compliance: RoHS compliance and MSL rating must be maintained
Series Compatibility: COMBICON DFK-IPCV series designation ensures functional interchangeability

The substitute part Phoenix Contact 1703250 meets all these criteria while offering active product status, ensuring long-term availability and supply chain continuity.

Engineering Selection Recommendations

The Phoenix Contact 1703098 serves as the direct functional substitute for the obsolete 1703250. Both components maintain identical electrical specifications (600V, 5A), mechanical pitch (0.400"), position count (6), and interface configuration. The 1703098 is classified as an active product, ensuring continued availability and supply chain support.

The primary distinction between the two parts is physical width: the 1703250 measures 4.017" (102.03mm) while the 1703098 measures 3.350" (85.08mm). This dimensional difference must be evaluated against specific panel layout requirements. Both parts maintain identical panel thickness compatibility (0.039 ~ 0.118") and mounting mechanism (2-piece snap lock).

Compliance certifications remain consistent across both parts: RoHS compliance and MSL rating of 1 (Unlimited) are maintained. Selection should be based on available panel space and dimensional constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 1703098 directly replace the 1703250 in existing installations?

A: Electrical and functional compatibility is complete. Physical width differs by 0.667" (16.95mm), requiring verification that panel mounting space accommodates the smaller 1703098 footprint.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components operate at 600V UL voltage rating with 5A current capacity and maintain identical pitch (0.400"), position count (6), and panel thickness range (0.039 ~ 0.118").

Q: What is the significance of the product status difference?

A: The 1703250 is classified as obsolete, indicating discontinued manufacturing. The 1703098 is active, ensuring long-term availability for procurement and future system maintenance.

Q: Do both parts use the same mounting mechanism?

A: Both employ 2-piece snap lock panel mounting. The 1703250 specifies "Front Flange" while the 1703098 does not include this descriptor, though both are mechanically compatible with the specified panel thickness range.

Q: Are RoHS and MSL certifications maintained in the substitute part?

A: Yes. Both the 1703250 and 1703098 are RoHS compliant with MSL rating of 1 (Unlimited), maintaining environmental and moisture sensitivity compliance.

Q: What packaging differences exist between these parts?

A: The 1703250 packaging is not specified in available data. The 1703098 is supplied in bulk packaging.
